My take on eating meat:
1) If you eat plants, you're not killing, but you are raping and pillaging the food source and/or homes of other animals and insects.
2) By eating higher up the food chain, you can extract more energy per creature eaten. Do you know how many vegetables you would need to eat have to consume same number of calories in a single cow?
3) It's nutritious and healthy.
Finally someone pointed out a few valid points.
Also it isn't that unhealthy to eat meat.
His points don't make much sense at all. And try eating a diet of only meat and see what happens.
